Good question, Brian.
They actually look very similar.
Both have the palpi 2nd segments(which covers the proboscis) large and bulging in front of the eyes.
Notocrypta (Demons) have more prominent palpi 3rd segments the 2 knobs which sit on top of the 2nd segments.
The body is brown; antennal club has a faint white patch ( not always seen in photos).
The shape of the white band (if exposed) is different.
The spot in space 4 may be present.
Quedara have the palpi 3rd segment almost invisible; a dark grey (blackish) body. No extra hyaline spot; different white band; antennal club black.
The male looks like a small Paintbrush Swift (
Baoris), but is unspotted, the palpi 2nd segments are bulging, & the hindwing cilia are dark grey.
